DC-DC Step down 6-24V to 5V 3A USB Charger Module

DC-DC Step-down 6-24V to 5V 3A USB Charger Module

Module parameters

Module nature: non-isolated step-down module (BUCK) synchronous rectification

Input voltage: DC 6-24V

Output voltage: 5.1-5.2V

Output current: Z is 3A (please pay attention to heat dissipation at full load), the actual test input is within 12V and the output is less than 2A without handling heat dissipation.

Conversion efficiency: 97.5% higher Z (6.5 to 5V 0.7A) (tested value after short connection of reverse connection protection and fuse)

Switching frequency: 500KHz

Output ripple: about 10mV (12V to 5V3A) 20M bandwidth

Output indication: the output voltage indicator is red

Working temperature: industrial grade (-40℃ to +85℃) (the higher the ambient temperature, the smaller the output power)

Output overvoltage protection: Yes, input 1.5A fuse, output 5V with 300W TVS tube.

Full load temperature rise: 30℃

Quiescent current: 0.85 mA
